Psychological Predictors of Pain and Disability in Patients With Chronic Low Back Pain After Manual Therapy

Greece60 participantsStarted 2025-12-10

Plain-language summary

Low back pain has been reported to cause more disability than any other musculoskeletal health condition worldwide. About eight out of ten people will experience back pain at least once in their lifetime. The parameters that are usually evaluated in a low back pain condition are pain, functional disability and range of motion of the lumbar spine. There are studies that associate psychological conditions (self-efficacy, kinesiophobia, catastrophology, depression, anxiety) with pain and functional disability in patients with low back pain. However, the ability of psychological factors to predict progression after a program of physical therapy or therapeutic methods is not well studied. The main purpose of this study is to investigate the predictive potential of psychological factors in the improvement of pain and functional disability after a manual therapy physiotherapy program in patients with chronic low back pain. A secondary purpose is to investigate the predictive potential of psychological factors in the improvement of pain and functional disability following a program of Pain Neuroscience Education (PNE) in patients with chronic low back pain. In addition, as a secondary purpose, it will be to investigate the effect of combining manual therapy therapy with PNE compared to manual therapy alone in patients with chronic low back pain. This study will involve 60 people aged 18-65 with chronic low back pain, who will be randomly divided by lots into 2 groups of 30 people. The 1st group (30 people) will be treated with manual therapy based on Maitland's principles (interview, evaluation, mobilization), without any use of physiotherapy machines, but with the use of personalized exercises. The 2nd group (30 people) will do the same as group 1 and additional volunteers will participate in before, in a training program in Pain Neuroscience Education (PNE). The total number of sessions that each volunteer will receive will be 6, the duration of each session will be about 45 minutes, the frequency of the sessions will be 2 times a week and the total duration of the intervention will be 3 weeks. The associations between psychological states and clinical characteristics (pain, disability and range of motion) will be carried out with the Pearson or Spearman correlation coefficient depending on whether the data are parametric or not. Multiple regression models will also be created with predictive factors for psychological states and a predictive variable for each of the clinical parameters. The significance level will be set to p=0.05.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
